GENE-CENTRICITY. “Missing pieces include how physical development influences the generation of variation (developmental bias); how the environment directly shapes organisms’ traits (plasticity); how organisms modify environments (niche construction); and how organisms transmit more than genes across generations (extra-genetic inheritance). For Standard Evolutionary Theory, these phenomena are just outcomes of evolution. For the Extended Evolutionary Synthesis, they are also causes.”
